It is "Snegurochka" - snowgirl , granddaughter of Ded Moroz Russian
version of Santa. Usually they displayed together as a pair under
Christmas tree during celebration of New Year.
It is so called "fancy serial number" note. Price depends on condition ,
type of serial number and how much somebody would pay for it. If it is
warned out I would try list it at $15 at an auction and then see what
happen. Good luck.
